Software for finite element analysis. Popular for analysis of structures subject to blast and impact loads in which high strain rates are observed. It has robust explicit solvers that are otherwise not available with other software packages. Pre-post is the pre-processing (model development) tool that comes with LSDYNA. Other preprocessors (e.g., MSC Patran, Hypermesh) are often used.
